Definitions

  • the present invention relates to an apparatus for needling a fibrous web, which comprises a row of needle beams arrayed adjacently each other in a direction of an operating width, the needle beams being adapted to be connected to exchangeable needle boards, means for driving the needle beams with the needle boards up and down in a reciprocating motion path, guidance means for the fibrous web, the guidance means comprising a fibrous web support and a stripper positioned between the needle beams and the support, and a conveyor device for conveying the exchangeable needle boards to and from the needle beams, the conveyor device extending alongside the row of needle beams.
  • a conveyor device which comprises revolving endless traction means arranged at each side of the needle beams outside the reciprocating motion path of the needle beams with the needle boards, and needle board entrainment elements in the form of bearing flanges for supporting side edges of the needle boards, the bearing flanges being carried by the traction means and being repositionable between a conveying position wherein they project into the reciprocating motion path and an inoperative position wherein they are outside the reciprocating motion path of the needle boards connected to the needle beams.
  • the needle boards only need to be disposed on the bearing flanges for entrainment by the traction means to the needle beams so that they may be lifted off the bearing flanges by the needle beams after they have been attached thereto. A return of assembly carriages or the like is avoided. The only thing required is to make sure that the bearing flanges are repositioned outside the reciprocating motion path during needling when the needle beams and attached needle boards move up and down.
  • the revolving endless traction means is comprised of an upper conveying strand and a lower return strand. This very much simplifies the conveyance of the needle boards to the revolving traction means since the needle boards only need to be pushed onto the traction means. Furthermore, the bearing flanges may be distributed over only a portion, for example over half, of the circumference of the revolving traction means. In this way, the mere continuing revolution of the traction means will move the bearing flanges from the conveying strand to the return strand and thus out of the reciprocating motion path of the needle beams with the attached needle boards. No further means are required for this.
  • the revolving traction means may serve as a carrier for a detachable cleaning device.
  • a cleaning device may be comprised of cleaning brushes or compressed air nozzles which are attached to the revolving traction means when it is desired to clean the stripper or the needle boards, which are in their raised position during such cleaning.
  • FIG. 1 is a fragmentary end view, partly in transverse section, of a needling apparatus according to the invention
  • FIG. 2 is an enlarged fragmentary sectional view of the apparatus, along line II--II of FIG. 1, during an exchange of the needle boards;
  • FIG. 3 is a corresponding view of the apparatus during needling when the bearing flanges are in the inoperative position.
  • an apparatus for needling a fibrous web which comprises a row of needle beams 1 arrayed adjacent each other in a direction of an operating width.
  • the needle beams are adapted to be attached to exchangeable needle boards 2 by conventional screw or clamping elements which may be operated automatically.
  • the needle beams are connected to push rods 3 driven by a reciprocating drive in any conventional manner.
  • the reciprocating drive is a crank drive, and a separate drive box associated with each needle beam is affixed to a carrier 4 which extends over the entire operating width.
  • a guidance means for the fibrous web comprises fibrous web support 5 and stripper 6 positioned between needle beams 2 and support 5.
  • the support and the stripper are perforated plates through whose holes the needles pass during needling.
  • Drives 7 are connected to carriers 13 of stripper 6 and may be actuated in unison for vertical adjustment of the stripper.
  • a conveyor device 8 for conveying the exchangeable needle boards to and from needle beams 1 extends alongside the row of needle beams.
  • this conveyor device comprises revolving endless traction means 10 arranged at each side of needle beams 1 outside the reciprocating motion path, and needle board entrainment elements 11 in the form of bearing flanges for supporting side edges of needle boards 2.
  • the bearing flanges are carried by traction means 10 and are repositionable between a conveying position wherein they project into the reciprocating motion path (FIG. 2) and an inoperative position wherein they are outside the reciprocating motion path of needle boards 2 attached to needle beams 1.
  • the revolving endless traction means at each side of needle beams 1 are preferably sprocket chains.
  • the chains trained about sprockets 9 run in guides 12 and are comprised of an upper conveying strand and a lower return strand.
  • the bearing flanges are distributed over only a portion of the circumference of revolving traction means 10, and in the illustrated embodiment, the bearing flanges are distributed over half the circumference of the revolving traction means. In this manner, half a revolution of the chain will move bearing flanges 11 from the upper conveying strand to the lower return strand, i.e. out of the reciprocating motion path of needle beams 1 with attached needle boards 2 during needling, as indicated in FIG. 3.
  • chain guides 12 are connected just above stripper 6 with carriers 13 of the stripper.
  • new needle boards 2 are conveyed through a gantry frame 14 at a side of the apparatus to the needling apparatus by a conveyor 14, which may be of a similar structure as conveyor device 10.
  • An input end of revolving endless traction means 8 adjoins an output end of conveyor 14 so that the needle board on conveyor 14 is transferred to conveyor device 10 where it rests on entrainment elements 11 to be conveyed underneath raised needle beams 1 (FIG. 2).
  • needle boards 2 may be attached to needle beams 1 in any conventional manner, for example by screws or clamps.
  • Stripper 6 is then lowered by drives 7 to lift the needle boards off entrainment elements 11 and traction means 8 is revolved by half a revolution to reposition the entrainment elements in the return strand (FIG. 3). In this position, entrainment elements 11 are outside the reciprocating motion path of needle board 2 during needling. The needle boards are removed from the needling apparatus by reversing the procedure.
  • the needle boards may be manually placed on, and removed from, conveyor 14 during an exchange or a needle board storage magazine may be provided adjacent conveyor 14 to deliver and receive the needle boards.
